Study on Chemical Constituents in Water Decoction of Fengshao Liujunzi

Objective:To reveal the chemical material foundation of active components in water decoction of Fengshao Liujunzi.Moreover,in order to develop and utilize them comprehensively,this paper studies the chemical constituents systematically.Method:According to extraction of the traditional decocting method,the components were isolated by silica gel column,Sephadex LH-20,macroporous adsorption resin D101,ODS-C18 repeatedly,and compounds structures were identified by spectral analysis.Result: Thirteen compounds were isolated and identified as β-sitoster(1),palmitic acid(2),isomultiflorenol(3),triacontanol(4),psoralen(5),atractylenolidⅢ(6),p-hydroxybenzaldehyde(7),gallic acid(8),benzoic acid(9),nobiletin(10),sinensetin(11),tangeritin(12),lactiflorin(13).Conclusion: thirteen compounds above were isolated from the decoction for the first time.Gallic acid may be one of the main active constituents of the decoction.
